You may see a lot of Henry Big Boys at shows, but you will not see very many at a CAS match. There are a bunch of reasons. I wouldn't touch one myself.
What about using a Remington Revolving Carbine?
No, a Remington Revolving Carbine is not a SASS legal rifle. From the shooter's handbook:
RIFLE REQUIREMENTS
Rifles or carbines used in the main and team matches must be original or replicas of
lever or slide action rifles manufactured during the period from approximately 1860 until 1899, incorporating a tubular magazine and exposed hammer. Rifles with box magazines may not be used. Certain shooting categories require a specific type of rifle and ammunition to be used. Please see the shooting categories for further information
RIFLE CALIBERS
Must be centerfire of at least .32 caliber and not larger than .45 caliber.
Must be in a caliber commonly available in revolvers. Examples include, bu
t are not limited to, .32-20, .32 Magnum, .357 Magnum, .38 Special, .38-40.44-40, .44 Special, .44 Magnum, and .45 Colt. The only allowed exceptions are the .25-20 and .56-50. No rifle calibers such as .30-30 or .38-55 are allowed.

Category competitors choosing to utilize .22 caliber firearms must use
standard velocity .22 caliber rimfire ammunition only.

Just got back from the show at the Big E, the biggest gunshow in Mass. Saw several original 1873 Winchesters. Wide variation in price and quality. Saw a couple for $2500 that were beaters. No I did not ask to take the wire tie off so I could open the action and peer down the bores. But you might be surprised. I have no problem buying an old revolver or rifle that has a pitted bore, as long as the rifling is still strong. I have bunches of old guns from the Black Powder era that have old pitted bores, but the rifling is still strong and they are good shooters.
There was one dealer who had very nice stuff and his prices were very reasonable. He had bunches of original 1892s and 1894s. He had two 1873s that were in very nice shape. One was a 38-40, the other was a 32-20. The 32-20 was made in 1887, I forgot to write down what year the 38-40 was made. He was asking $1695 for each, a very reasonable price based on what I have seen. I suspect he could have been talked down a little bit. In fact, I was tempted to bargain with him over the 38-40, but I already have one and didn't want to spend that much today. If I had that one, I would not hesitate to bring it to a match and shoot it with Black Powder loads. I would not shoot the bezeezus out of it, I would shoot it relatively slowly and deliberately and I would not slam it down on the loading tables or props.

I forgot to mention earlier that refinished originals are a very good option if you want an original. Refinishing old guns knocks the collector's value way down and you can get a nice looking refinished original for much less than usual. The first rifle I used in CAS was a very nice original Winchester Model 1892 that had been made in 1894. It had been refinished, so it was very affordable. I used this rifle for my first two years in CAS.
This 1916 era 1892 Saddle Ring Carbine was very affordable because it had been refinished. I found it a few years ago. I think I paid less than $500 for it. I ran right up to the counter and bought it before they changed the price.
Of course if you are buying refinished guns, you better know one when you see one. Some dealers will be right up front and tell you it has been refinished. Those are the guys you want to do business with. Others may try to fool you into thinking it is the original finish. Walk away from those guys.
